Hair Dye Horror!

well I think the first question that needs to be asked is did your mom get her hair dyed at the salon or did she use a at home kit? I'm courious as to what brands they were if she did them at home. If this happened at a salon you mom may want to look into getting a lawyer. Because it is mandatory for a salon to do an allergy test when you get your hair colored. Many salons do not do this but if someone has an allergic reaction like your mom did they could get into big test. The salon is suppose to put a little of the coloring on your arm or behind your eye. And your suppose to let it stay there for 24 hours. If you have no reaction to the dye than they can color it. You are not suppose to be able to walk into a salon and get a color job done on your hair that same day if it's your first time at the salon, or if the salon decides to change the brand of coloring they used. It sounds like your mom has dermatitis. Its not the ammonia in the dye that your mom is allergic too. Many hair colors contain a chemical called paraphenylenediamine also known as PPD. P.P.D. helps give the dye a natural looking color when placed in the hair and helps the color from fading after being washed. You said your mom used black. well the darker the color used the more P.P.D. there will be. Your mom may want to try using semi permanent hair coloring or temporary hair coloring which will wash out after so many washes. But the P.P.D count in these types of coloring is much lower than it is in permanent coloring. If it is P.P.D that your mom is allergic too she can go for a brand called natural henna or Elumen which is manufactured by the goldwell company. They are the only coloring company that has hair coloring which contains no P.P.D what so ever. you should check into the P.P.D. allergic reaction because many of the symptoms your are describing sounds exactly like the reaction from this chemical. You have to remember that no all allergic reactions surface right away. Some can take years to develop. So since your mom has been dying her hair for years, and P.P.D has been around since the 1980's/ it is very likely that she has develops this reaction from the amount of p.p.d. over the years. Hope I was some help.

i think, before she dye her hair she must visit the dermatologist first

I don't have any tips, but I just bought a box of hair die today. I usually buy the same brand but different colors depending on my mood (typically a shade of red). Anyways, I actually decided to read the instructions and the inside of the box says to do an allergy test every time you dye your hair - even if you are using the same brand and same color you always use because you can have a sudden allergic reaction. Not saying I do this, but after reading your post, maybe I will. Maybe she was on a medication or had a change in diet that some how reacted to the dye or maybe the manufacturer change what they use to make the dye. Maybe she should mix the dye and do the allergy test?
